我想買部netbook ar！
大約$5000，
Asus s101 定Samsung NC 10 好？

Since your budget is around $5000, I think Asus N10J is a good choice, it is slightly more expensive than the other models, but it can play HD very well since it has Nvidia 9300m GS. You can switch to integrated graphics for longer battery life, about 6hours.

MSI U100 $3499
MSI 3G HSPA $4250 宜入 SIM 卡
160GB 2GB RAM 6 Cells
